Hey there!
In our slope-intercept equation, b is the y-intercept, where the line crosses the y-axis. In our case, that happens to be -5, because that's where the line intersects the axis.
Now, we're finding m, or the slope. The slope is defined as rise over run. We can use our slope given two points formula, y2-y1/x2-x1 to find the slope.
For our two points, we'll use the intercept: (0,-5) and the other intercept: (6,0)
Let's plug in our values:
0-(-5)/6-0 =
5/6
Therefore, 5/6 is the slope.
Hope this helps!

I am wondering if the answer to this question is Table B. At x = 1, f'(x) = 1/2. At x = 2, f'(x) = 3. Does this mean that, betwe
noname [10]
I agree. The answer is choice B

=========================================================

f ' (1) is shown to be positive
f ' (2) is shown to be positive as well
There are no critical values between x = 1 and x = 2, so f ' (x) is positive on the interval 1 < x < 2, so f(x) is increasing on this interval

All of this points to either choice A or choice B

--------------------------------

Similarly, 
f ' (3) is negative
f ' (4) is negative
so f ' (x) is negative where 3 < x < 4 due to no other critical values being between x = 3 and x = 4

Based on these facts alone, the answer is either choice B or choice D

But we know that it can't be choice D as we determined it was between A and B. This rules out choice D

So all that's left is choice B

Which ordered pairs are solutions to the inequality 2x+y&gt;−4?
hichkok12 [17]

we will proceed to resolve each case to determine the solution

we have

2x+y>-4

y>-2x-4

we know that

If an ordered pair is the solution of the inequality, then it must satisfy the inequality.

<u>case a)</u> (5,-12)

Substitute the value of x and y in the inequality

-12>-2*5-4

-12>-14 ------> is True

therefore

the ordered pair (5,-12) is a solution of the inequality

<u>case b)</u> (-3,0)

Substitute the value of x and y in the inequality

0>-2*-3-4

0>2 ------> is False

therefore

the ordered pair (-3,0) is not a solution of the inequality

<u>case c)</u> (-1,-1)

Substitute the value of x and y in the inequality

-1>-2*-1-4

-1>-2 ------> is True

therefore

the ordered pair(-1,-1) is a solution of the inequality

<u>case d)</u> (0,1)

Substitute the value of x and y in the inequality

1>-2*0-4

1>-4 ------> is True

therefore

the ordered pair (0,1) is a solution of the inequality

<u>case e)</u> (4,-12)

Substitute the value of x and y in the inequality

-12>-2*4-4

-12>-12 ------> is False

therefore

the ordered pair (4,-12) is not a solution of the inequality

<u>Verify</u>

using a graphing tool

see the attached figure

the solution is the shaded  area above the line

The points A,C, and D lies on the shaded area, therefore the ordered pairs A,C, and D are solution of the inequality
